Document SRC_GPR10 PERSIST_SECONDARY_BOOT functionality. This is useful for
reliable bootloader A/B updates, as it permits switching between two copies
of bootloader at different offsets of the same storage. The switch happens
in case one copy is corrupted OR can be enforced by user. This functionality
is present at least since i.MX53, however is poorly documented in all known
SoC datasheets, hence this document aims to clarify the usage, currently on
i.MX7D and i.MX8MM.

For FSL_USDHC, it do not implement VENDORSPEC_CKEN/PEREN/HCKEN/IPGEN, these
are reserved bits. Instead, use VENDORSPEC_FRC_SDCLK_ON to gate on/off the
card clock output.
After commit b5874b552f ("mmc: fsl_esdhc_imx: add wait_dat0() support"),
we meet SD3.0 card can't work at UHS mode, mmc_switch_voltage() fail because
the second mmc_wait_dat0 return -ETIMEDOUT. According to SD spec, during
voltage switch, need to gate off/on the card clock. If not set the FRC_SDCLK_ON,
after CMD11, hardware will gate off the card clock automatically, so card do
not detect the clock off/on behavior, so will draw the data0 line low until
next command.

commit 03f1f78a9b ("spl: fit: Prefer a malloc()'d buffer for loading images")'
changed the way buffer allocation worked for SPL to a more flexible
method.
For venice this caused breakage that is resolved by increasing the size
of CONFIG_SYS_SPL_MALLOC_SIZE as the current FIT slighly exceeds 512KiB.
Additionally remove the unnecessary comment on CONFIG_SPL_BSS_MAX_SIZE
and CONFIG_SYS_SPL_MALLOC_SIZE as the size is obvious from the define.

Add a weak nand_get_mtd function for nand drivers to provide mtd info
and use this to set pagesize such that reading of non page-aligned

The spl_load_simple_fit already handles block block access so all we

Further cleanup of the drivers which use nand_spl_loaders.c such as

using info from mtd_info instead of statically defined details.
